Rep. Tammy Duckworth (D., Ill.) skipped a congressional vote to help Holocaust victims on Tuesday so that she could fundraise with the liberal Middle East lobbying group J Street, which has a reputation for promoting an anti-Israel agenda.

A liberal Middle East advocacy organization long accused of pursuing an anti-Israel agenda is currently touring the Jewish state with several members of Congress and organizational donors, according to information provided to the Washington Free Beacon.

The left-leaning Middle East activist group J Street, one of the key groups that lobbied in favor of the Obama administration’s nuclear deal with Iran, hosted a fundraiser for the Senate campaign of Rep. Tammy Duckworth.

The controversial J Street PAC announced it will center its attention on attempting to unseat Republicans who led efforts to oppose President Obama’s Iran nuclear deal and will focus on Sen. Ron Johnson (R., Wisc.) during the 2016 elections, according to the Times of Israel.

Top White House allies are mounting a campaign to discredit recent reports Iran will be responsible for investigating its own military facility for evidence of nuclear activities under an agreement between international inspectors and Tehran.

Former Wisconsin Democratic Sen. Russ Feingold, who is attempting to take back the Senate seat he lost to Republican Sen. Ron Johnson in 2010, received over $35,000 in bundled lobbyist contributions despite previously leading the push against lobbyist money and for full disclosure from bundlers.
